5 Best Audi TT Performance Upgrades
1. Full Air System
Getting more power from your TT means allowing the car to breath. After all, the engine needs
oxygen to combust fuel, and planting a cool air intake and header-back exhaust system is one of the
most inexpensive and effective ways to see power gains. Since the TT’s stock cams only feature two
exhaust valves, a ported performance cam will allow a greater exhaust flow out of the engine.
2. Fuel Upgrade
Be sure to tune the car’s fuel to air ratio whenever you replace an intake system, as a change in
airflow without subsequent change in fuel volume will minimize power increase and potentially
damage the engine’s internal components. An aftermarket fuel pressure regulator will allow you to
achieve a greater fuel input to match the upgraded air system. High flow injectors are also key to
maximizing power from these systems.
In order to handle the increase in power, it is important to have adequate suspension. The TT’s
magnetic suspension already makes for a sporting drive, however some previous models use
standard dampers and coils. To dramatically improve ride performance, “spring” for an upgraded
suspension, preferably with fully adjustable shocks, so that you may tweak their performance at
Possibly the greatest single power jump any modification can give you, outfitting the TT with a high
capacity turbocharger is among the most popular modifications available. It’s not just bolt on and
start up though, the engine’s diverter valve must be uprated, and the heads must be replaced with
the ported and polished variety fitted with a three-angle valve job. Finally, a remap is essential.
The most popular turbo is the KO4, as it requires the least amount of engine adjustment to work
5. Alloys and Brakes
A nice set of alloys will allow the brakes to cool off faster, and look snazzy to boot. Be wary however, as getting a larger set of wheels will alter drive ratio and affect performance, especially acceleration.
There are ways to counter this, but it is recommended to keep the total diameter of the wheel and
tire the same. Therefore, if you want rims an inch bigger than stock, get tires with an inch narrower
profile. This will avoid a lot of headaches in the future.
Making the TT faster is one thing, stopping it is a whole other ball game. Bear in mind there are
three main parts to the brakes to consider when upgrading, and ignoring any of them could severely
impede their performance.
- Rotors- The convention for performance rotors is cross-drilled to allow them to breath, though
material is equally important for cool down rate and durability. Go with an alloy designed to handle
heat without warping.
- Calipers- These contain the pistons that drive the brake pad into the rotor. A six-piston variety will cover a large surface area and stop on a dime.
- Pads- Performance pads will create more friction, reducing that “spongy” feel during heavy
